Abstract
Having established an easy approach to a new class of pyridinium-1-aminides bearing an N-perfluoroacyl residue, we studied the influence of the polari ty of the solvent on the maximum absorption in the UV/vis spectra. N-perflu oroaeyl-pyridinium-1-aminides have a strong interaction with the solvent de termining negative solvatochromic effects which have been correlated with t he E-T(30) polarity parameters. Some relative quantum yields of the title a minides as fluorescence emitters are also reported and they show an interes ting structure dependence. (C)1999 Elsevier Science S.A. All rights reserve d.
